Description

Technical Field

[0001] The utility model relates to a connecting structure for adjacent railway box beam ends. Background Art

[0002] Railway is a land transportation method that uses locomotives to pull train vehicles on two parallel rails. The traditional method is steel wheel travel, but the broad definition of railway transportation also includes non-steel wheel travel methods such as magnetic levitation trains, cable cars, ropeways, etc., or rail transportation. Rails can provide an extremely smooth and hard medium for train wheels to roll on with minimal friction, making people on them feel more comfortable, and it can also save energy. If properly configured, rail transportation can save 50% to 70% of energy when carrying the same weight of goods compared to road transportation. In addition, rails can evenly distribute the weight of the train, greatly improving the train's load-bearing capacity.

[0003] With the rapid development of my country's economy and the continuous development of the railway network, the construction scale of four-line railway continuous beams has been continuously expanded. However, the existing two-span simply supported box beams adjacent to the continuous beams have problems with insufficient integrity, bending resistance and torsional resistance, which affects the safety and stability of the structure. Therefore, a beam end connection structure of adjacent railway box beams is proposed to solve the above problems. Utility Model Content
